CLEANER AND GAUGE FOR WINDING MACHINES.

7 Application filed April 14:, 1921. Serial No. 461,403.

To all whomz't may concern Be it known that I, MAURICE N. WEIN- scram, a citizen of the United States, residing at: East'Cleveland, in the county of Guyahoga and State of Ohio, have invented a certain new and useful Improvement in Cleaners and Gauges for Winding Machines, of which the following is a full, clear, and exact description, reference being had to the accompa'nying drawings.

This invention is a novel construction of cleaner and gauge used in connection with machines for winding wool, silk Or other material, and the object of the invention is to provide an exceedingly cheap and simple device which is capable of accurate adjustment, one whichcan be quickly and easily attached to any of the various types of machinesnow in use and one which will be more durable than the cleaners now' employed.

Itis well known that wool, silk and similar material, as manufactured, contains certain imperfections eitherin the way of for eign matter adhering to the threads, or eX- cess of material at certain points. and inasmuch as a uniform dimension of thread or strand is desired in knitting and weaving, it is customary in winding the strand to 3 clean or scrape the same so as to remove all surplus or foreign matter so that the thread or strand as finally wound, will be of uniform dimension. While cleaners or scrapers have been employed in connection with various types of winding machines, they have proven only partially successful, owing to the difficulty of accurate adjustment and for various other reasons. As before stated, the object of my invention is to M provide a simple and improved device which willremedy these various defects.

With these objects in view my invention consists in the novel features of construction and in the manner of combining or arranging the same, all of which will be here inafter fully described and set forth in the appended claims.

In the drawings forming a part of this specification, Fig. 1 is a face view of one 59 form of cleanerembodying my invention; Fig. 2 1s a side view of the same; Fig. 3is a.

.; longitudinal sectional view on the line 3- -a3 of Fig. 2; Fig. 4 is a transverse sectional view on the line 44; of Fig. 1 and Fig. 5 is a transverse sectional view on the line 55 of Fig. 1. In the practical embodiment of my invention, I employ an arm A which is connected to any suitable portion of the machine frame A and it will be understood that this arm A can be arranged either vertically, or horizontally and can be either straight or bent, it being intended only as a carrier andmeans ofattachment for connecting my improvedcleaner in its proper position with reference to the machine frame. The cleaner proper embodies a pair of blocks B and C to which are connected the cleaner blades 1) and E, respectively. The block B is rigidly connected to the arm or rod A through the medium of a screw or bolt F and it will be understood that the arm or rod .A may enter the block B from the end as shown in the drawings; or it can be entered at the side. The rod or arm A, being rigidly connected to the machine frame and the block 13 being connected thereto, the block C is adjustably connected to the block B through the medium of an adjusting screw G which passes through the block C and screws into the threaded bore G of the block B. A coi spring I-I surrounds the screw G and is held in the counterbored portions of the openings through which the screw passes. the tendency of the spring being to force the block C away from the block D and the screw Gr is provided with a head G which sets in a counterbored recess in the face of the block C. It is obvious that by turning the screw in the desired direction the block C can be caused to move toward or away from the block B. The head G of the screw is provided with graduations and the face of the block C is also graduated so that by turning the screw a definite amount in either direc tion, a definite and accurate movement of the block C can be obtained.

In order to guide the block C in-its movements and insure parallelism at all times, I employ a guide finger I which is rigidly connected to the block C and projects aterally therefrom and is preferably square in cross sectlon as shown, said finger sliding 1n a guideway cut 111 the'blo'ck D as most clearly shown. The hardened steel blades D and E are connected to the front faces of the blocks B and C by means of set screws D and E, respectively, and the blade D is provided with an elongated opening-orslot D through which a set screw L passes into the threaded bore I produced in the guide finger I, this set screw being tightenedafter tlw blades have been adjusted to the desired position by turning the screw Gr in the proper direction, and it will of course be understood that previous to any adjustment it will be necessary to loosen theSet screw L.

The front faces of the blocks B and-C are planed off from end to end, leaving stop flanges B and C, respectively, along the outer edges thereof and against which the blades D and E are positioned before tightening up the screws D and E, respectively.

The blocks B and C are also provided with opposed recesses .or bores B and C respectively, to receive the glass or porcelain roller M over which the yarn or silk-travels as it passes between the cleaning blades D and E.

It will be noted that there is suificient clearance between the roller and the'bores so that said roller will turn freely in the blocks inalso insures easier operation of the device as a whole and also permits the roller to be quickly and easily removed in case of break age or impairmentand the substitution of a new roller. The block 13 is preferably made longer than the block C and the blade D is also preferably made longer than the blade E. In practice I prefer to cut away the end of the blade E adjacent the blade D, as most clearly shown at E and also round oil the end of the blade E as shown at E Shaping the blade E in this manner facilitates the introduction of the yarn, thread or strand, into the space between the cleaning blades, and this relative arrangement of I the bladeends is the same, irrespective of whether the blades project downwardly as shown, or upwardly .or horizontally.

lVhile I have shown the set screw L as applied to the longer block and blade, it

will, of course, be understood that it can also be applied, if desired, to the shorter block and blade. vIn practice, I also prefer to cut away the front face of the guide finger l as indicated at I- in Fig. 4 so that the gauge strip can be readily inserted between the blades when desired, as without this cut away port-ion the gauge strip could not be fully lnserted between the edges of the blades adjacent their upper ends. also preferred to provide the head G of the screw G with openings G sospaced as'to receive the lugs of an adjusting key (not shown) carried by the master mechanic, so that the screw cannot be tampered with by the operator of the machine, it being desirable to have the blades set by the master mechanic only and not interfered with by anyone.

It "will thus be seen z-that I provide an exceedingly cheap and simple device which can be quickly and easily connected to any of the present types of winding machines. It will alsobe noted that the device is capableofquickand easy adjustment by simply loosening the set screw L and turning the screw G in the desired direction, and by means of graduations upon the screw head and the side of the block, a definite amount of movement can be insured by a definite movement of the screw head.

Furthermore, parallelism of movement is obtained through the medium of the guide finger I and by virtue of the stop flanges attheysides of the blocks, absolutely accurate positioning of the blades with refer ence to said blocks is always assured. By means of the free running-glass or porcelain roller-the wear uponthe roller is reduced to a minimum and the free and easy passage of the yarn or strand between the blades is facilitated. r

Should any of the parts become broken or impaired, they can be quickly and easily removed and new ones substituted. The blades, if desired, can be made reversible.

Having thus described my invention, what I claim is:

In a device of thekind described the combination with a fixed member-having a recess, of "a movable member, a screw pass ing through the movable member and engaging the fixedmember and a spring surrounding'said screw and bearing upon the contiguous faces of both members, a guide rigidly connected to the movable member and working in a recess produced in the fixed member, blades attached to the fixed and movable members, the blade of the fixed member being slotted and a set screw passing through the. slot of said blade and engaging the guide in the fixed member.

2.
